To say something is “too much” or “too small” or that we drank “too much” and so forth, we use the verb ぎる.

Adjectives

For i-adjectives we remove the い and add すぎる.

たかすぎる。
Too high/expensive.

And because it’s now treated as a verb we can use the te form; however, note that the object still requires the が particle.

パソコンがたかすぎていませんでした。
The computer was too expensive so I didn’t buy it.
こわすぎる。
Too scary.
映画えいがこわすぎて、最後さいごまでられなかった。
The movie was too scary so I couldn’t watch until the end.

For na-adjectives we just add すぎる without the auxiliary verb or な particle.

複雑ふくざつすぎる。
Too complicated.
この数学すうがく問題もんだい複雑ふくざつすぎるから、明日あした先生せんせいきます。
This maths problems is too complicated so I’ll ask the teacher tomorrow.

Verbs

For verbs we need to use the verb stem.

昨日きのうぎて、あたまいたいですよ。
I drank too much yesterday—my head hurts!
